Nikki Collins (Deanna Durbin) witnesses a murder while waiting for a train, but can’t get the police to believe her when no body is discovered. While they dismiss her as daft, she enlists the help of a mystery writer to sleuth out the culprits on her own. Based on a story by veteran mystery scribe Leslie Charteris (The Saint), this is a wildly entertaining mix of comedy, musical and suspense, rendered in evocative noir style by cameraman Woody Bredell (PHANTOM LADY, CHRISTMAS HOLIDAY, THE KILLERS), and featuring a superb cast of sinister and suspicious supporting players (including noir fave Dan Duryea) who swirl ominously around “America’s Sweetheart.”
